rious words or signs.

It is an object of the invention to provide a device of this characterin which yieldlng sleeves made integrally with the metallic platesurround the holes and extend backwardly at substantially right anglesto the plate to form a sleeve which resiliently holds the light bulbs inthe plate.

The drawings illustrate by way of example a preferred embodiment of theinvention. Figure 1 is a fragmentary plan View of an advertising deviceaccording to the invention.

Figure 2 is a transverse section through line AB of Figure 1.

Figure 3 shows in a larger scale a fragmentary plan view of the metallicplate from which tongues have been cut, the tongue being not yet bent toproject back of the plate;

Figure 4 is a section through line CD of Figure 3, the tongues beingbent backwards to form a sleeve for insertion of electric light bulbs.

The advertising device consists of a thin metal plate 1 provided with agreat number of equidistant holes 2 which are adapted to receive thecaps of electric light bulbs 3. The plate 1 is secured to a casing 4 andsurrounded by a frame 5.

The holes 2 are obtained by cutting and stamping the plate 1 so thatyielding tongues 6 are formed and bent in 7, Figure 3, so as to projectbackwardly from the plate at substantially right angles, as seen inFigure 4. The triangular shaped tongues shown in Fig. 3 are given asexample only, these tongues could also be otherwise shaped withoutdeparting from the spirit of the invention.

The width of the tongues decreases from their base towards their freeend so that the resiliency of the ends of the tongues is increased andthe tongues disposed around one hole form a sleeve yieldingly holdingthe cap of electric bulbs, for instance, as shown, ordinary bulbs withEdisoncaps.

It is therefore sufiicient, in order to secure a bulb to the plate 1, topush the bulb in a hole Where it-will be held 'by the tongues, and inorder to remove a bulb from the plate a simple traction has to beexerted on the bulb.

The metal plate 1 is connected to one of the poles of a sourceof currentso that the plate with the tonguesforms a conductorwhich brings thecurrent to the cylindrical part of the bulb caps.

A metallic grating 8 is placed at a certain distance from the plate 1,as seen in Figure 2, and is connected to the other pole of the source ofcurrent. i This grating 8 makes contact with the end faces of the bulbcaps.

In order to ensure a good contact between the bulb caps and the grating8, this latter is placed on a resilientcushion consisting for instanceof felt. The cushion is secured to a rigid back plate 10 fixed to thecasing 4;.

The objectof the grating 8 is to give the entire contact surface auniform elasticity permitting the establishment of contact for a greatnumber of lamps. r

The bulbs 3 can be inserted into the holes 2 to form any desired word orsign, in the example given in Fig. 1 the bulbs are disposed to form theletters D A N.

The provision of sleeves by cutting tongues from the metal platesupporting the bulbs is a great advantage for the manufacture ofadvertising signs since the device according to the invention, althoughcomprising a great number of holes for the insertion of bulbs, canbemanufactured at relatively small cost because it does not require anyspecial sleeves or lamp holders for screwing or otherwise locking thebulbs, which lamp holders would necessitate a great number of connectingwires and attachments.

The invention is not limited to the example as described and shown inthe drawings. Various dispositions and combinations of ad vertisingsigns can be obtained without departing from the scope of the appendedclaims. There can be used colored or uncolored bulbs with metallicfilament or neon lamps.

I claim 1. In an electric advertising device the combination of a metalplate provided with a number of holes adapted to receive electric lightbulbs, tongues struck from the material of the plate and bent backwardsalong the edges of the holes in the plate substantially at right anglesto the plate to form a resilient sleeve extending rearwardly from eachhole and adapted to resiliently engage the cap of the electric bulb, aresilient cushioning memberpositioned in the rear of said metal plate,and a metallic grating covering the face of the cushioning memberopposite the metal plate, said cushioning member being in such spacedrelationship to the metal plate that the caps of the electric bulbsinserted through said holes make contact with the grating.

2. A holder for electric bulbs comprising in combination, a metal plateincluded in an electric circuit, tongues struck from the material of theplate and bent backwards at substantially right angles to the plate toform a circular opening in the plate and a resilient sleeve extendingbackwards from the opening and adapted to receive the cap of theelectric I bulb with a sliding fit, a resilient cushion p0- sitioned inthe rear of the metal plate, and a metallic grating included in thecircuit and covering the face of the cushion opposite the metal plate,said cushion being in such spaced relationship to the metal plate thatthe cap of thebulb inserted through said opening makes contact withthegrating and thereby closes the circuit between the latter and themetal plate.

In testimony whereof I afiix my signature.
